Who made the first Hybrid automobile?

Who made the first successful American Hybrid Vehicle?

William Morrison around 1890.

You can read up on his invention here: https://www.american-automobiles.com/Electric-Cars/Morrison-Electric.html

How did the USA contribute to the modern rebirth of the hybrid vehicle?

With the passage into law of the the Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976 in response to rising gas prices, associated shortages (think of the kind of queues Nigeria is known for) and worst of all the Arab Oil Embargo of 1973.

Very strong possibility that the 2021 Sienna is going to be a hybrid

Would you buy one?

Hi, I have a 2006 Toyota Highlander Hybrid.
The 12v battery was changed recently and I noticed the "check vsc system" error code.

Now, it displays both "check hybrid system" and "check vsc system" error codes. It won't show ready when I start until I disconnect and reconnect the negative battery terminal.

I had someone scan it for me and I got the following codes.

Seen. Will get back to you.

The ABS actuator (ABS pump) is likely faulty.

@oshosegun27:The VSC associated codes you got, are not the root cause(s) of the READY light not coming onboard.

The VSC related codes comes on, when the hybrid system also has an issues. Remember, the VSC, in this case, ABS actuator, skid control, etc, would automatically ceased to function, if there's a problem with the hybrid system of your car.

So in this case, as long as the car isn't coming to READY, and only comes on when you disconnect and connect the 12V battery back, suggests to me that you've a HIGH VOLTAGE ISOLATION PROBLEM(meaning, there's a leakage of high voltage from the hybrid system, to vehicle chassis or ground). This is dangerous, and means you'd have to be disconnecting the 12V at every stops, to fool the system into thinking all is well.

The above scenario is a likelihood though, since we don't have any codes right now, as regards high voltage leaks.

Here's what to do with your code reader:
Get a code reader that is capable of retrieving hybrid related codes, especially ENGINE AND HYBRID SYSTEM. Almost all cheap scan tools should be able to retrieve store codes I the engine system.

There are a lot of scenarios that could caused the car not to go into READY asides the one I mentioned above.

A weak or dead hybrid battery would never come to ready, no matter what you do.


Hope this helps you some bit?

Thanks a lot for all your inputs.

The skid control ecu was replaced and ISC relearn was performed.

The car is okay to an extent.

However, the "check vsc system", some brake lights and a continuous beep come on at intervals for less than 2 minutes then go off completely.
